Description

Intraocular intraocular lens contact lenses having a mechanism for anchoring by the anterior leaflet of the capsular body wall, related systems and methods

FIELD OF THE INVENTION The present invention relates generally to implantable optics. More particularly, the present invention relates to intraocular intraocular intraocular lens contact lenses and mechanisms and related systems and methods for anchoring by an anterior leaflet of the capsular wall.

In a normal human eye, light enters through the cornea and passes through the pupil, and the natural lens focuses the light on the retina of the eye. However, due to cataracts or other problems, it is necessary to replace the eye's natural lens with an artificial intraocular lens (IOL). The term “pseudophakia” is used to describe an eye in which a natural intraocular lens has been replaced by an intraocular lens.

Before the intraocular lens is placed on the patient's eye, the physician or other staff member typically selects an intraocular lens designed to provide the desired refractive correction to the patient's eye.

For example, an intraocular lens could have an optical lens designed to correct for myopia (near-sightness), hyperopia (far-sightness), astigmatism or other refractive errors that occur naturally in the patient's eye. can

However, it is often the case that the intraocular lens selected for the patient's eye does not fully correct (and may even cause) some form of refractive error in the patient's eye. This refractive error is referred to as a “residual” refractive error.

There are various conventional solutions for correcting the residual refractive error, but all of them have disadvantages.

For example, one intraocular lens in a patient's eye may be replaced with another intraocular lens, but this generally has a high risk of surgical complications.

Resection surgery (such as LASIK) of the cornea of a patient's eye can be performed to correct the residual refractive error, but it is very likely to lead to unwanted side effects, especially in elderly patients.

An additional intraocular lens (sometimes referred to as a “piggyback” IOL) may be inserted in front of the existing intraocular lens, but this is typically an invasive surgery with less predictability associated with the final refractive outcome.

Moreover, while an intracorneal lens (ICL) can be inserted into the cornea of a patient's eye, it is often more invasive and carries a very high risk of failure. In general, such surgeries are typically unpredictable and have a high level of surgical risk.

Also, since the devices used in the surgery are difficult to eliminate and "reverse" the residual refractive error, this leads to the accompanying visual aberrations that are dangerous to the patient to a very high degree.

1 to 38 described below, and various embodiments used to describe the principles of the present invention in this patent document are merely illustrative and should not be construed as limiting the scope of the present invention.

Those of ordinary skill in the art will understand that the principles of the present invention may be embodied in any form of suitably arranged apparatus or system.

The present invention provides a variety of intraocular pseudophakic contact lenses (IOPCLs) that can be used with intraocular lenses (IOLs).

An intraocular intraocular lens contact lens generally refers to a contact lens-like device that can be implanted in a patient's eye and placed on the anterior surface of the intraocular lens in the patient's eye.

In some embodiments, the intraocular intraocular lens contact lens substantially corrects residual refractive errors that exist after implantation of the intraocular lens, such as after cataractectomy (cataract) surgery.

In another embodiment, the intraocular intraocular lens contact lens provides some other form of vision correction when placed on the intraocular lens of a patient's eye.

Furthermore, the intraocular intraocular lens contact lens may include haptics or other mechanisms such that the intraocular intraocular lens contact lens may be constrained (constrained)/captured (captured) by the anterior leaflet of the capsular wall in the patient's eye. do.

In some cases, the haptic or other mechanism may actually attach to the anterior leaflet of the capsular body wall, such as through fibrosis during the healing process, which helps to hold the intraocular intraocular lens contact lens in place.

Unlike conventional approaches, intraocular intraocular lens contact lenses can be implanted with reduced surgical risk.

Moreover, the intraocular intraocular lens contact lens allows the patient to see immediately after implantation of the intraocular intraocular lens contact lens.

In addition, other lenses can be easily replaced if necessary, or removed as needed, to correct for residual refractive errors or to provide some other form of vision correction.

In addition, currently available techniques such as intraoperative wavefront aberrometry can be used to measure refractive results during the actual surgery in which intraocular intraocular intraocular lens contact lenses are implanted, which helps to immediately identify that the desired refractive target is achieved. give

1 to 3 show an intraocular intraocular lens contact lens 100 of a first embodiment according to the present invention.

In particular, FIG. 1 shows a perspective view of an intraocular intraocular lens contact lens 100 , FIG. 2 shows a plan view of the intraocular intraocular lens contact lens 100 , and FIG. 3 shows an intraocular intraocular lens contact lens 100 . shows a side view of

1 to 3 , the intraocular intraocular lens contact lens 100 includes an optical lens 102 .

The optical lens 102 represents a portion of the intraocular IOL contact lens 100 that modifies the light passing through the intraocular intraocular lens 100 .

Light passing through the optical lens 102 then travels through the associated intraocular lens before reaching the retina of the patient's eye.

The optical lens 102 may be formed from any suitable material(s), such as silicone or acrylic.

The optical lens 102 may also be formed in any suitable manner, such as, for example, using a mold or lathe cut manufacturing process.

Other lenses 102 may be designed and manufactured to provide a wide range of diopters, and each optical lens 102 may be designed to correct for any suitable refractive error(s) or other suitable vision correction. .

Exemplary forms of refractive error that can be corrected include myopia, farsightedness, and astigmatism.

The optical lens 102 in this embodiment has a convex top surface and a concave bottom surface. However, the optical lens 102 may have any other suitable shape, which may depend (at least in part) on the type of refractive error(s) being corrected or other vision correction being made.

As a specific example, the optical lens 102 may be convex, concave, spherical, aspherical, toric, monofocal, or multifocal.

The particular lens platform used as the optical lens 102 in the intraocular intraocular lens contact lens 100 may be selected to provide a desired refractive correction or other vision correction in the patient's eye.

The optical lens 102 may also be configured such that, for example, the optical lens 102 is self-orienting on the intraocular lens in a desired orientation (such as relative to an astigmatism platform). may include various other characteristic parts as needed or desired, such as when weighted (as in), or when the optical lens 102 is tinted, and also photochromic, or ultraviolet (UV) light. ) may contain absorbents.

Multiple haptics 104a - 104b extend from multiple sides of optical lens 102 . The haptics 104a - 104b are sized and shaped such that they extend a short distance from the optical lens 102 and fit under the anterior leaflet of the capsule wall in the patient's eye after implantation.

Each haptic 104a - 104b may be formed from any suitable material(s) and in any suitable manner.

For example, each haptic 104a - 104b may be formed of the same material(s) as the optical lens 102 . Although only two haptics 104a - 104b are shown, the intraocular intraocular lens contact lens 100 may include any number of haptics, including a single haptic.

It is also noted that while the haptics 104a - 104b are angled downward, the haptics 104a - 104b may have any other suitable arrangement.

In this embodiment, the haptics 104a - 104b are separated from the optical lens 102 by protrusions or extensions 106 that protrude from the side of the optical lens 102 .

These extensions 106 represent a portion of the intraocular intraocular lens contact lens 100 in which the ends of the haptics 104a - 104b may be embedded. Each extension 106 may be formed from any suitable material(s) and in any suitable manner.

For example, each extension 106 may represent a portion of the material(s) forming the optical lens 102 , and thus may represent an extension of the optical lens 102 itself. However, this need not necessarily be the case.

For example, the optical lens 102 may be positioned within a support ring integral with or attached to the extension 106, or the extension 106 may be attached to the optical lens using an adhesive or other suitable connection mechanism. 102) may be fixed to itself.

Although two extensions 106 are shown herein, it should be noted that the intraocular intraocular lens contact lens 100 may include any number of extensions, including a single extension.

It should also be noted that the provision of the extension 106 is not necessary and the haptics 104a - 104b may be directly integrated with the optical lens 102 .

In these embodiments, the haptics 104a - 104b may represent some of the material(s) forming the optical lens 102 , but need not be so.

For example, the optical lens 102 may be positioned within a support ring integral with or attached to the haptics 104a-104b, or the haptics 104a-104b may use an adhesive or other suitable connection mechanism. Thus, it may be fixed to the optical lens 102 itself.

Each of the haptics 104a - 104b includes a textured surface 108 , in this embodiment the texturing surface 108 is a variety of holes formed partially or fully through the haptics 104a - 104b. are formed using

The texturing surfaces 108 allow haptics 104a - 104b to be captured and confined by the anterior leaflet of the capsular wall in the patient's pseudophakic eye.

In some cases, the texturing surface 108 may have haptics 104a - 104b actually physically attached to the anterior leaflet of the capsular body wall in the patient's eye, such as through fibrosis during the healing process. to be adhered to

The haptics 104a - 104b help hold the intraocular intraocular lens contact lens 100 in place on the intraocular lens. It should be noted that the number and size of holes in texturing surfaces 108 are for illustrative purposes only and haptics 104a - 104b may include different numbers and sizes of holes.

For example, the haptics 104a - 104b may include a very large number of very small holes or other structures forming a texture that facilitates constraint (confinement), capture or attachment to the anterior leaflet of the capsular body wall. may be

The anterior leaflet of the capsular body wall in a patient's eye is typically created during a capsulotomy in which the natural capsular lens is removed from the patient's eye and replaced with an intraocular lens.

The anterior leaflet represents the lateral portion of the anterior aspect of the capsular bag that remains after an opening (referred to as capsulotomy) has been formed in the capsular bag so that the natural capsular lens can be removed.

In some cases, this may occur long before the intraocular intraocular intraocular lens contact lens 100 is implanted. After capsulotomy, the anterior leaflet of the capsular body wall typically contracts during the healing process and undergoes fibrosis.

When the intraocular intraocular lens contact lens 100 is inserted into the patient's eye, the intraocular intraocular lens contact lens 100 may be positioned such that the haptics 104a - 104b extend below the anterior leaflet of the patient's eye. . This allows the haptics 104a - 104b to be captured and constrained by the front leaflet.

The haptics 104a - 104b may also be physically attached to the anterior leaflet over time, for example through “re-fibrosis” of the anterior leaflet. Re-fibrosis of this tissue adheres to cover some or all of the haptics 104a-104b, and further fixes the intraocular intraocular lens contact lens 100 in place.

However, it should be noted that the intraocular intraocular lens contact lens 100 may also be implanted during the same procedure as an intraocular lens is implanted. In this case, the intraocular intraocular lens contact lens 100 may be immobilized during fibrosis (and not refibrosis) by means of haptics 104a - 104b and possibly within the patient's eye.

The intraocular intraocular lens contact lens 400 also includes one or more pins 410 .

Each pin 410 projects downwardly from an extension 406 or from an inner end of the haptics 404a - 404b.

The pin(s) 410 may be used to puncture the anterior surface of the intraocular lens or to rest on the anterior surface of the intraocular lens.

In addition to capturing/limiting the haptics 404a - 404b by the anterior leaflet, the pins 410 further support the intraocular intraocular lens contact lens 400 in place and the It can help resist slipping.

In some cases, the pins 410 are responsible for the haptics 404a-404b of the intraocular IOL contact lens 400 during the period immediately following implantation in the patient's eye (such as through refibrosis) of the capsule wall. It can be used to prevent movement of the intraocular intraocular intraocular lens (IOL) contact lens 400 before being adhered to the anterior leaflet.

Each fin 410 may be formed from any suitable material(s) and in any suitable manner. Although two pins 410 are shown herein, the intraocular intraocular lens contact lens 400 may include any number of pins, including a single pin.

Also, although pins 410 are shown herein as having sharp ends, this need not be the case.

For example, the pin 410 may have round or blunt surfaces, which may help to place the pin 410 (not perforated) on the anterior surface of the intraocular lens.

Moreover, although pins 410 are shown herein as extending through or embedded in extension 406 , pins 410 may be located in any other suitable location(s).

For example, the pins 410 may be moved to the outer end of the haptics 404a-404b, or an additional pin 410 may be located at the outer end of the haptics 404a-404b.

As described above, the intraocular intraocular lens contact lens 400 may be implanted during the same procedure as the intraocular lens is implanted or during a subsequent procedure after the intraocular lens has already been implanted in the patient's eye.

The anterior leaflet of the capsular body wall of the patient's eye may be used to capture and constrain the haptics 404a-404b of the intraocular intraocular intraocular contact lens 400 below the anterior leaflet, optionally haptics 404a-404b in the patient's eye. Fibrosis or refibrosis may occur to adhere 404a-404b).

For example, the intraocular intraocular lens contact lens 1600 includes an optical lens 1602 and multiple haptics 1604a - 1604b.

The haptics 1604a - 1604b are formed by larger protrusions extending from the side of the optical lens 1602 .

Each of the haptics 1604a - 1604b is connected to an inner portion 1606 connected to an optical lens 1602 (or to an inner portion 1606 connected to a support ring on which the optical lens is supported) and the inner portion 1606 connected to the inner portion 1606 . and an outer portion 1608 that is

The outer portion 1608 has a thickness that tapers towards the outer edge of the haptics 1604a - 1604b, which in the patient's eye allows for easier insertion of the haptics 1604a - 1604b under the anterior leaflet of the capsular wall. to facilitate

Each of the haptics 1604a - 1604b also includes a ridge 1610 , wherein the plurality of ridges 1610 of the plurality of haptics 1604a - 1604b captures one or more edges of an underlying intraocular lens. can be used to capture).

This may help position the intraocular intraocular lens contact lens 1600 in the center of the intraocular lens. It may also help hold the intraocular intraocular lens contact lens 1600 in place on the intraocular lens during the healing process.

Moreover, the intraocular intraocular lens contact lens 1600 herein includes a number of segments 1612 positioned along the side of the optical lens 1602 .

The segments 1612 represent a projection from the optical lens 1602 , and at least some of the segments 1612 (eg, as when the ends of the haptics 1604a - 1604b are embedded in the segment 1612 ). ) haptics 1604a - 1604b.

The segments 1612 extend downward such that the bottom surface of the segments 1612 is positioned below the optical lens 1602 .

As a result, when implanted in a patient's eye, segments 1612 keep optical lens 1602 separate from the lower intraocular lens.

Depending on the shape of the posterior surface of the optical lens 1602 and the shape of the anterior surface of the lower intraocular lens, this may raise the optical lens 1602 above the optical lens in the lower intraocular lens so that the optical lenses do not contact each other.

Each of the segments 1612 may be formed from any suitable material(s) and in any suitable manner.

For example, each of the segments 1612 may represent a portion of the material(s) forming the optical lens 1602 and thus represent an extension of the optical lens 1602 itself. However, this need not necessarily be the case.

For example, the optical lens 1602 may be positioned within a retaining ring integral with or attached to the segments 1612 , or the segments 1612 may be connected using an adhesive or other suitable connection mechanism. It may be fixed to the optical lens 1602 itself.

Each of the segments 1612 may also have any suitable size, shape, and dimension. For example, segments 1612 may be smaller or larger (for other structures) than those shown in FIGS. 16-18 .

The ability to space the optical lens 1602 away from the lower intraocular lens can provide various advantages.

For example, raising the optical lens 1602 above the lower intraocular lens may cause an increase in aqueous flow between the anterior surface of the intraocular lens and the posterior surface of the optical lens 1602 .

The enhanced aqueous flow between the lenses reduces lens deposition to either or both of the lenses. In addition, the presence of aqueous solutions between the lenses can help improve the optical or image quality of the combined lens system.

Moreover, by providing more space between the lenses, the intraocular intraocular lens contact lens 1600 can be used as a wider range intraocular lens with variable anterior curvature surfaces, which is an intraocular intraocular lens contact lens. Allows 1600 to be used with a wider range of ocular lens models and powers.

It should also be noted that the size and shape of the lens portions 3412-3414 may be varied as needed or desired.

While various prior approaches have fixed “add-on” lenses to intraocular lenses, these prior approaches do not contain specific additions ( It requires an add-on lens and a specific intraocular lens that must be designed for use with that particular add-on lens.

That is, the additional lens can be used only with a specific type of intraocular lens, and the intraocular lens is specifically designed for use with the additional lens.

As a specific example, the additional lens may include a haptic or other structure designed to mate with a corresponding structure of a particular intraocular lens, or the intraocular lens may have a recess designed to receive an additional lens of a particular shape. can have

This can be problematic for a number of reasons. For example, many patients already have an existing intraocular lens, and it may be impractical or even risky to remove an existing intraocular lens to implant a new intraocular lens designed for use with an additional lens.

The embodiments of the intraocular intraocular lens contact lens shown in FIGS. 1-36 include the intraocular intraocular lens contact lens using the anterior leaflet of the capsular body wall to capture and confine the haptics of the intraocular intraocular lens contact lens. This can help alleviate problems like this because it can be fixed over the lens.

In some cases, this may also include physically adhering the haptics to the anterior leaflet of the capsular body wall, for example via a fibrotic or refibrotic mechanism.

In other words, the intraocular intraocular lens contact lens need not be specifically designed to work with any particular intraocular lens specific structure.

The intraocular lens used with the intraocular intraocular lens contact lens need not have any predefined structure provided for coupling to the intraocular intraocular lens contact lens.

Rather, the intraocular intraocular lens contact lens of Figures 1-36 is captured by (and possibly adhesively) the anterior leaflet of the capsule wall when the intraocular intraocular lens contact lens is placed over the intraocular lens. It may simply be sized so that it can be held in place through restraints.

This allows the intraocular intraocular lens contact lenses of FIGS. 1-36 to be used with a wide variety of intraocular lenses, including various types of intraocular lenses and conventional intraocular lenses already implanted in the patient.

There is no need to remove the existing intraocular lens from the patient to fit new intraocular lenses and intraocular intraocular lens contact lenses.

Furthermore, the intraocular intraocular lens contact lenses of FIGS. 1-36 may be haptic to the capsule wall or after implantation, for example (assuming that fibrosis or refibrosis holds the intraocular lens in place) or the contact lens is in place. They can be easily removed from the patient's eye at any suitable time, such as prior to bonding them.

Among other things, this allows one intraocular intraocular lens contact lens to be removed and replaced with another intraocular intraocular lens contact lens if other refractive correction or other vision correction is needed or desired.

The various intraocular intraocular intraocular lens contact lenses described above may have any suitable size, shape, and dimension.

For example, the intraocular intraocular lens contact lens may be made available in a diameter range of about 4 mm to about 6 mm.

In addition, the intraocular intraocular lens contact lens may be provided by changing various basic curvatures for the optical lens.

Of course, the intraocular intraocular lens contact lens may also be custom designed for a particular patient's eye, such as where one or more specific curvatures are required to correct residual refractive errors or provide other desired vision correction in the particular patient's eye.

The intraocular intraocular lens contact lenses described herein may be implanted non-invasively into the eye of a patient and may also be readily placed in the intraocular lens.

Because the intraocular intraocular lens contact lens is mounted on the anterior surface of the intraocular lens, implantation is non-invasive, which is typically readily accessible by a surgeon or other staff during the implantation procedure.

In addition, implantation is non-invasive as the intraocular intraocular lens contact lens can be attached to the intraocular lens without the need to attach it to an anatomical structure within the patient's eye, for example the suclulus of the patient's eye. .

The non-invasive implantation and easy positioning of the intraocular intraocular lens contact lens is a safe and effective refractive surgery procedure for correcting unwanted residual refractive errors or providing any other desired vision correction, for example, a phacoepicectomy procedure. provides

As a refractive modality, the intraocular intraocular lens contact lens alters the current refractive error of an intraocular lens patient or otherwise alters the intraocular lens patient's vision in an effort to adjust the patient's vision to achieve a fine-tuned desired refraction. contributing to the surgeon's ability to

Specific examples of the above functions include adjusting the patient's eyes to achieve unilateral or bilateral emmetropy, inducing unilateral myopia to allow intermediate and near-sighted functions, introducing multifocals, and reducing unwanted residual astigmatism. can be treated

If the haptics of the intraocular intraocular lens contact lens include ridges along its bottom, the ridges may be used to center the intraocular intraocular lens contact lens on the lower intraocular lens as described above.

If the intraocular intraocular lens contact lens includes three haptics with associated ridges, the ridges may help to perfectly center the intraocular intraocular lens contact lens on the lower intraocular lens.

This approach allows the ridges of the haptics of the intraocular intraocular lens contact lens to capture the lower intraocular lens at the edge and perfectly align the optical center of the intraocular lens with the optical center of the intraocular intraocular lens contact lens. .

Such alignment helps to reduce or avoid induced optical aberrations or induced prisms caused by optical center misalignment. This offers a strong contribution advantage over traditional refraction fine-tuning methods.

It should be noted that, in any of the above embodiments, the intraocular intraocular lens contact lens may be designed such that only the haptics of the intraocular intraocular lens contact lens extend under the anterior leaflet of the capsular body wall in the patient's eye.

Thereby, the optical lens of the intraocular intraocular lens contact lens allows haptics to be captured and constrained by the anterior leaflet while being free and not normally obscured by the surrounding tissue of the patient's eye.

It is also noted that, in some embodiments, intraocular intraocular lens contact lenses may be implanted using the surgical tools disclosed in US Patent Application Serial No. 16/280,235 (which is incorporated herein by reference in its entirety).

For example, the tool may be used to separate at least a portion of an anterior leaflet of a patient's eye from an implanted intraocular lens, which allows the haptics of an intraocular lens contact lens to be inserted between the anterior leaflet and the intraocular lens.

In another embodiment, the tool may be used to separate the anterior leaflet of a patient's eye from an implanted intraocular lens contact lens, which allows for removal (and replaceable) of the intraocular intraocular lens contact lens.

Moreover, it should be understood from the above description that a variety of optical lenses or other optical devices may be used as the optical lens of any given intraocular intraocular intraocular lens contact lens. This allows an intraocular intraocular lens contact lens to be used to provide a variety of vision corrections for the patient's eye when combined with the intraocular lens of the patient's eye.

As noted above, for example, the intraocular intraocular lens contact lenses may help correct myopia, farsightedness and/or astigmatism refractive errors in a patient's eye.

As another example, the intraocular intraocular lens contact lens provides magnification to a low vision patient, provides focus guided through an adjusted prism, and/or a variable aperture (eg, pinhole, cat eye structure and/or or or constriction slits).

As another example, the intraocular intraocular lens contact lens provides various forms of vision correction (multifocal, astigmatism, depth of focus, asymmetric cornea and/or photochromic correction), provides drug delivery, provides UV protection, and and/or may be used to support treatment of photooptic disorder.

In general, the present invention is not limited to any particular form or shape of an optical lens in an intraocular intraocular lens contact lens or to any particular form of treatment using an intraocular intraocular lens contact lens.

Although Figures 1-36 show an example of an intraocular intraocular lens contact lens, various modifications may be made to Figures 1-36.

For example, any suitable combination of the features shown in FIGS. 1-36 may be used together in a single intraocular intraocular lens contact lens, regardless of whether a particular combination of functions is shown in the figures or described above.

In particular embodiments, any of the intraocular intraocular lens contact lenses shown in FIGS. 1-36 may include one or more pins in one or more desired positions, a haptic ( ), one or more ridges along the bottom surface(s), and/or one or more lips to aid in capture of the intraocular lens.

Further, each intraocular intraocular lens contact lens may include any suitable number of each component shown in any figure.

Although the figure shows an intraocular intraocular lens contact lens as having 2, 3 or 4 haptics (some evenly spaced at 120° or 180°), (with associated pins, ridges, lip or other structures Any number of haptics (with or without) may be used.

Also, the form of the haptics shown herein is exemplary only, and other suitable structures may be used to capture (capture), constrain or attach the anterior leaflet of the capsular body wall in the patient's eye.

In addition, a number of other characteristic elements may be used at one or more locations of an intraocular intraocular lens contact lens.

For example, one or more alignment markings can be provided to identify proper alignment of the intraocular lens and the intraocular intraocular lens contact lens, or the one or more drug eluting substances in the intraocular intraocular lens contact lens, the upper surface of the optical lens. , may be located on the side or bottom.

37 illustrates an exemplary intraocular lens and an exemplary intraocular intraocular lens contact lens for a patient's eye 3700 in accordance with the present invention.

37 , eye 3700 includes a cornea 3702 , a sclera 3704 , and an iris 3706 .

The cornea 3702 represents the transparent anterior portion of the eye 3700 that allows light entering the eye 3700 to pass. The sclera 3704 is the rough outer white part of the eye. The iris 3706 controls the pupil size of the eye to control the amount of light that enters the eye 3700 from the cornea 3702 .

The eye 3700 also generally includes a capsular bag 3708 that holds the natural lens of the eye 3700 .

However, in this embodiment, the natural lens is removed and replaced with an intraocular lens 3710 having an optical lens 3712 and one or more haptics 3714 . The optical lens 3712 of the intraocular lens 3710 receives light entering the eye and focuses the light on the retina of the eye 3700 .

The haptics 3714 of the intraocular lens 3710 are used to support the intraocular lens 3710 within the capsular bag 3708 such that the optical lens 3712 of the intraocular lens 3710 is in a desired position within the eye. help

The intraocular intraocular lens contact lens 3716 is also located in the intraocular lens 3710 within the capsular bag 3708 .

The intraocular intraocular lens contact lens 3716 may represent any intraocular intraocular lens contact lens described above or any other suitable intraocular intraocular intraocular lens contact lens.

The intraocular intraocular lens contact lens 3716 is positioned on the anterior surface of the intraocular intraocular lens 3710 , which means the front surface (anterior surface) of the intraocular intraocular lens 3710 with respect to the eye 3700 .

Light enters through the cornea 3702 and passes through the pupil before entering the intraocular intraocular lens 3716, which modifies the light.

The modified light passes through the optical lens 3712 of the intraocular lens 3710 and is modified again. The twice-corrected light then travels through the rest of the eye 3700 to reach the retina at the back of the eye 3700 .

As noted above, the intraocular intraocular lens contact lens 3716 includes one or more haptics that extend a short distance and fit under the anterior leaflet 3718 of the capsular bag 3708 . This allows the haptics to be captured and confined by the anterior leaflet 3718 (and also to attach to the anterior leaflet 3718, possibly via fibrosis or refibrosis).

The anterior leaflet 3718 represents the lateral portion of the anterior surface of the capsular bag 3708 that remains after a capsular incision is made in the capsular bag 3708 .

Inserting the haptics of the intraocular intraocular lens contact lens 3716 under the anterior leaflet 3718 helps to secure the intraocular intraocular lens contact lens 3716 in place.

In some cases, the healing process of the eye 3700 can cause fibrosis, which also allows the anterior leaflet 3718 to attach to the haptics of the intraocular intraocular intraocular lens contact lens 3716 .

It should be noted that the haptics of the intraocular intraocular lens contact lens 3716 are shorter or smaller than the haptics 3714 of the intraocular lens 3710 .

This is because the haptics 3714 of the intraocular lens 3710 generally extend to the top and bottom of the capsular bag 3708 , which helps to support the intraocular lens 3710 in an appropriate position within the capsular bag 3708 . do.

The haptics of the intraocular intraocular lens contact lens 3716 do not need to extend to the top and bottom of the capsular bag 3708 , but may instead extend only a short distance below the anterior leaflet 3718 .

By properly selecting the optical lens of the intraocular intraocular lens contact lens 3716 , the intraocular intraocular lens contact lens 3716 ideally corrects for any residual refractive error remaining after implantation of the intraocular lens 3710 . or provide any other desired vision correction in the patient's eye 3700 .

If necessary, the intraocular intraocular lens contact lens 3716 may be removed and replaced with another intraocular lens contact lens.

This may be the case if the intraocular intraocular lens contact lens 3716 does not adequately correct residual refractive error, if the intraocular intraocular lens contact lens 3716 actually causes additional refractive error, or any other form of vision Calibration may be necessary or desirable where necessary or desired.

Although FIG. 37 shows one example of an intraocular lens and one example of an intraocular intraocular lens contact lens in a patient's eye, various modifications may be made to FIG. 37 .

For example, the intraocular lens 3710 may be attached to any other intraocular intraocular lens contact lens. In addition, there are a number of intraocular lenses available, and an intraocular intraocular lens contact lens may be coupled to other suitable intraocular lenses of the eye 3700 .

38 illustrates an exemplary method 3800 for using an intraocular intraocular lens contact lens with an intraocular lens in accordance with the present invention.

As shown in FIG. 38 , a residual refractive error of the patient's eye with an intraocular lens is identified in step 3802 .

This may include, for example, personnel testing the patient's vision and identifying any refractive errors remaining after implantation of the intraocular lens 3710 .

Testing can be done in any suitable manner, such as using intraoperative wavefront aberration measurements.

One goal of the test is to determine if there are any refractive errors in the patient's eye after an intraocular lens is implanted in the patient's eye.

This test can be performed at an appropriate time, such as after a phacoectomy. However, this step is optional because intraocular intraocular lens contact lenses can be used to provide other forms of vision correction to the patient's eye and do not necessarily correct residual refractive errors.

In step 3804, an intraocular intraocular lens contact lens (IOPCL) is selected, for example to correct an identified residual refractive error or to provide some other form of vision correction.

This may include, for example, a person selecting an intraocular intraocular lens contact from a kit, the selected intraocular intraocular lens contact lens having an optical lens that substantially neutralizes the identified residual refractive error.

This may also include the staff selecting an optical lens from the kit and inserting the optical lens into an intraocular intraocular lens contact lens, wherein the selected optical lens substantially cancels the identified residual refractive error.

It may further include an agent obtaining an intraocular intraocular lens contact lens having a custom designed optical lens, or obtaining a custom designed optical lens for insertion into an intraocular intraocular lens contact lens, wherein the custom designed optical lens is identified It substantially eliminates residual refractive errors.

It may also include personnel obtaining (in any way) intraocular intraocular lens contact lenses that provide the desired amount of magnification (magnification), multifocal or other form of vision correction.

In general, any mechanism can be used to obtain an appropriate intraocular lens contact lens.

The selected intraocular intraocular lens contact lens is inserted into the patient's eye at step 3806 . This may include, for example, a surgeon or other staff making a small incision in the patient's eye and inserting an intraocular intraocular lens contact lens through the incision into the eye.

The intraocular intraocular lens contact lens may be rolled up, folded, or reduced in cross-sectional size to insert the intraocular intraocular lens contact lens through a smaller incision.

One or more haptics of an intraocular intraocular lens contact lens are inserted under the anterior leaflet of the capsular bag wall in the patient's eye at step 3808 .

This may include, for example, a surgeon or other staff placing the intraocular intraocular lens contact lens 3716 in a desired location (and possibly in a desired orientation) on the intraocular lens 3710 .

It may also include a surgeon or other staff member moving the intraocular intraocular lens contact lens 3716 (in any form) such that the haptics slide under the anterior leaflet 3718 of the intraocular lens bag 3708 .

A vision test for the patient occurs at step 3810 .

The visual acuity test may be performed in any suitable manner, such as using, for example, intraoperative wavefront aberration measurements. This vision test may be performed at an appropriate time, such as during surgery to implant an intraocular intraocular lens contact lens or after surgery is complete.

At step 3812, a determination is made as to whether the tested visual acuity is satisfactory. This could include, for example, staff determining whether and to what extent the patient's eye is still experiencing any residual refractive error. This may include staff determining whether the patient's eye requires additional magnification, multiple focus, or other forms of vision correction.

In step 3814 a determination is made whether to change the intraocular intraocular lens contact lens.

This may include, for example, staff and patients determining whether residual residual refractive error (if any) is uncomfortable or otherwise problematic for the patient, or otherwise determining whether current vision correction is insufficient. have.

If so, you can take other steps to solve the problem.

For example, the cylinder axis correction can be adjusted by repositioning the currently implanted intraocular intraocular lens contact lens.

If this fails, at step 3816 another intraocular intraocular lens contact lens is selected. This could mean, for example, that an employee selects another intraocular intraocular lens contact lens that provides better refractive or other vision correction for the patient's eye (ideally) compared to the currently inserted intraocular intraocular lens contact lens. may include

The currently inserted intraocular intraocular lens contact lens is removed from the patient's eye at step 3818 . This may include, for example, a surgeon or other staff sliding (sliding) the haptics of a currently inserted intraocular intraocular lens contact lens 3716 from below an anterior leaflet 3718 and a currently inserted intraocular intraocular lens contact lens ( 3716) from the patient's eye.

The process then returns to step 3806, where the newly selected intraocular intraocular lens contact lens may be inserted into the patient's eye and the vision test may be repeated.

After the procedure shown in FIG. 38 is complete, the haptics of the implanted intraocular intraocular lens contact lens 3716 may be captured/constrained by the anterior leaflet 3718 of the capsular bag 3708 in the patient's eye.

This helps to hold the intraocular intraocular lens contact lens 3716 in place. Moreover, the healing process of the patient's eye can optionally result in fibrosis or refibrosis, which physically attaches the haptics of the implanted intraocular intraocular lens contact lens 3716 to the anterior leaflet 3718 of the capsular bag 3708 . can do.

Although FIG. 38 shows one example of a method 3800 for using an intraocular intraocular lens contact lens with an intraocular lens, various modifications may be made to FIG. 38 .

For example, although depicted as a series of steps, the various steps of FIG. 38 may overlap, occur in parallel, occur in a different order, or occur multiple times.
